OK, I'll dig it up tonight, scan it, and put it on the web and post the
schematic.

I guess Philips owns Signetics now, the part number for data sheets is SA571.

NE570 is the better spec version of the NE571.

$3.29 for an NE571 at www.jameco.com
$2.25 for an NE570 at www.bgmicro.com

Cheers,

Bob
